Abstract:	We report results on time-dependent CP asymmetries in B -> D(-/+)pi(+/-) decays based on a data sample containing 657 x 10(6) B (B) over bar pairs collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider at the Y(4S) resonance. We use a partial reconstruction technique, wherein signal B -> D(-/+)pi(+/-) events are identified using information only from the fast pion from the B decay and the slow pion from the subsequent decay of the D(-/+), where the former (latter) corresponds to D(+)(D*(-)) final states. We obtain CP violation parameters S(+) = +0.061 +/- 0.018 (stat) +/- 0.012 (syst) and S(-) = +0.031 +/- 0.019 (stat) +/- 0.015 (syst).
